Depending on how much the stunter stunts, there are kits to put an an additional or replacement oil pickup at the back instead of where it is currently in the front. That way the bike is always getting oil even during wheelies and 12'oclock riding. Like I said, Im not sure if it is an additional pickup or just a re-location kit for the current pickup. I would think relocation kit so you dont loose oil pressure through one of the pickups.
